Graffiti removal can be a time consuming and expensive task. Tackle the job yourself and avoid the hassle of repainting and resurfacing. First, prepare and protect the surface with a mixture of Activator (No. 153668) and Urethane Finish (No. 153667). Mixture is 0.84-gal. (short-filled gal.) of Finish with 0.16-gal. (short-filled qt.) of Activator to create 1-gal. of solution. Apply solution to any interior or exterior concrete, brick, masonry, wood or previously coated surface. Once prepared you can rest assured the Graffiti Remover (No. 153669) will safely dissolve all unsightly markings. Remover washes out spray paint, markers, crayon, inks and adhesive residues without damaging base coatings.
